UUP: Bullish Dollar ETF Captures Long-Term Momentum

Is this bullish Dollar a real trend changer?

UUP: Bullish Dollar ETF Captures Long-Term Momentum - Seeking Alpha: "One explanation for this rally is recent dollar intervention and changes in the U.S. International Reserve Position. The U.S. Treasury website recently reported that the Exchange Stabilization Fund sold 10 billion euros and bought dollars, a move that certainly strengthened one currency against the other. It is difficult to claim that measures like this could sustain a dollar rally—the foreign exchange market is the largest in the world, and broad measures by international banks might be curbed by inflation worries abroad.
So could currency intervention be enough to cause, or sustain, a true rally in the dollar and UUP? Other possible causes of a reversal are the price of oil and falling demand in U.S. markets. In an interview on August 8, Marc Faber noted: “As a result of weak demand in the U.S. and lower imports, the demand for oil declined, and that led to a tightening of global liquidity, which led to the strong dollar.”"
